Double Trap Escape

Abstract A 55-year-old man was diagnosed with gastric adenocarcinoma. 18 F-FDG PET/CT was performed, which detected an enlarged nodule with increased uptake located in the omentum between the transverse colon and liver, thus lymph node metastasis was under suspicion. The patient subsequently underwent 68 Ga-FAPI PET/MRI clinical trial after signing the informed consent, which also revealed the abnormal focus with intense uptake. However, the histopathology of the nodule was unexpectedly diagnosed as fibrous hyperplasia after lymphadenectomy.
